Figure 3: Reversible 2D crystallization as a function of [NaCl].

From: Observing classical nucleation theory at work by monitoring phase transitions with molecular precision

Figure 3

(a) At 10 mM NaCl, 2D crystals are readily formed, which after washing with 25 mM NaCl (b) fully redissolve to nucleate anew (c) when the [NaCl] is lowered again to 10 mM. Note that the number density of clusters is lower (compared with a) due to the shorter delay time between sample injection and the onset of imaging. The bulk composition was 0.05 mg ml−1, 10 mM Hepes pH 7.0, 50 mM MgCl2 and 10 mM and 25 mM NaCl.
